 [Swagger](http://swagger.io) tooling for Rails API's. Generate beautiful API documentation, including a UI to explore and test operations, directly from your rspec integration tests.
 
-Rswag extends rspec-rails "request specs" with a Swagger-based DSL for describing and testing API operations. You describe your API operations with a succinct, intuitive syntax, and it automaticaly runs the tests. Once you have green tests, run a rake task to auto-generate corresponding Swagger files and expose them as YAML or JSON endpoints. Rswag also provides an embedded version of the awesome [swagger-ui](https://github.com/swagger-api/swagger-ui) that's powered by the exposed file. This toolchain makes it seamless to go from integration specs, which youre probably doing in some form already, to living documentation for your API consumers.

+#### Supporting multiple versions of API #### 
 By default, the paths, operations and responses defined in your spec files will be associated with the first Swagger document in _swagger_helper.rb_. If your API has multiple versions, you should be using separate documents to describe each of them. In order to assign a file with a given version of API, you'll need to add the ```swagger_doc``` tag to each spec specifying its target document name:
